Description
Technical field
The utility model belongs to the cigarette filter production technical field, and is particularly related to a kind of reducing tar and reducing harm cigarette filter composite filter.
Background technology
Along with the progressively enhancing with environmental consciousness of improving constantly of people's living standard, and country is to the attention of reducing cigarette tar and reducing harm reduction, and novel filter material and reducing tar and reducing harm means become the focus and the difficult point of tobacco business personnel research.In present reducing tar and reducing harm means, mainly come reducing tar and reducing harm by the moulding compound bar, add charcoal compound bar, dust-free paper as the vinegar fibre and add the modes such as compound bar of the compound bar of charcoal and the fine moulding of vinegar and recycled writing paper and the moulding of vinegar fibre the further reducing tar and reducing harm of cigarette, perhaps improve filter efficiency by measures such as lengthening filter length, raising resistance to suctions, but the filter stick that exceedingly extends partly is the smoker to be difficult to accept, and the degree of raising resistance to suction also is limited.
In existing reducing tar and reducing harm means, the technology that the vinegar fibre adds the charcoal compound bar is ripe, and part has dropped into tobacco market.But because the vinegar fibre adds the moulding process of carbon rod is to apply active carbon in becoming rod motion, by the mode that coats active carbon is added in the diacetate fiber, therefore is very difficult to guarantee to apply evenly.In addition, also need add the special charcoal equipment that adds.Secondly, do not have bonding fastness between active carbon and the tow, compound bar is relatively more difficult when cigarette factory cigarette.Moreover, because active carbon lacks bonding fastness, therefore in forming process, easily dropping, utilization rate is low, easily pollutes cigarette equipment, the subsequent treatment difficulty.More expensive, the complex forming technology of raw material in addition, so cost is higher, uses so be only limited in the high-grade cigarette at present.
The patent No. is that the utility model patent of ZL 20072006244.5 discloses a kind of dry method paper (claiming dust-free paper again) that utilizes and adds the compound compound bar of the fine rod of carbon rod and vinegar.As everyone knows, dust-free paper mainly is to add the part meldable fibre in wood pulp cellulose, perhaps sprays a spot of glue again and reaches the purpose that improves dust-free paper intensity.But, still can not satisfy the high-speed molding requirement of dust-free paper filter stick with regard to present dust-free paper intensity.Secondly, dust-free paper lacks enough elasticity, and the filter stick of moulding occurs heat easily when connecing the cigarette suction and subsides.Moreover, because dust-free paper mainly reaches certain intensity by the bonding wood pulp cellulose of meldable fibre, therefore when moulding, be prone to the dry linting problem, and the health of this point when aspirating for the smoker is very important.So by the end of at present, the fine compound bar of dry method paper and vinegar also is difficult to the application that puts goods on the market.
It is a kind of by recycled writing paper and the compound filter rod of acetate fiber that the patent No. is that the utility model patent of ZL200720086952.5 discloses.The weak point that the utility model exists is that filter efficiency is low, and has tangible papery gas during suction, has destroyed the flue gas mouthfeel, can not be subjected to consumer's favor.
Japan filter tip Co., Ltd. develops the Wood pulp non-woven fabrics filter tip material in twentieth century, and is applied in the composite filter tip material as a kind of filtering material efficiently.Obviously, changed the arrangement mode of material filter stick as filter-tip material from macroscopic view, formed mixed and disorderly three dimensions screen, therefore improved a lot aspect the raising filter efficiency with Wood pulp non-woven fabrics.Detect to find that filter stick is under same resistance to suction, the filter efficiency of Wood pulp non-woven fabrics filter stick is apparently higher than the fine filter stick of traditional vinegar, and its reason is that a large amount of polarity hydroxyls of existing in any arrangement of wood pulp cellulose in the Wood pulp non-woven fabrics and the cellulose chain are (OH).This point is very important for making flue gas softer.Adopting Wood pulp non-woven fabrics is that wood pulp cellulose belongs to Biodegradable material as another advantage of filter material of cigarette, therefore helps environmental protection.But pure Wood pulp non-woven fabrics filter stick hardness in high humidity environment descends very obvious, flue gas drying when connecing the cigarette suction, and occur heat easily and subside.
